Migrate data using windows deduplication function to FSx(windows)

Question

Hello  
  
Currently, 100TB of data is compressed to 50TB using the deduplication function of Windows.(EC2 on AWS)  
I want to migrate this data to FSx for windows.  
(The FSx pricing structure costs because of storage and throughput capacity)  
  
ec2⇒robocopy⇒FSx for windows  
  
However, if you remove the deduplication function when performing data migration, the data capacity will return to 100 TB and a lot of costs will be incurred.  
  
Is there a specific way to migrate data to FSx with the data deduplicated?  
We want to reduce the cost and migrate data to FSx.  
  
I want to use windows robocopy as the data migration method.

Answer

Thank you !

Hi fuka,  
  
In this case, you can create an Amazon FSx file system that is closer to the size you expect to get to - 50 TB. As soon as you create the Amazon FSx file system, you can enable Data Deduplication, and set the Deduplication optimization schedule to run aggressively (see our documentation for details on how to set the schedule: https://docs.aws.amazon.com/fsx/latest/WindowsGuide/using-data-dedup.html). When you then initiate the copy of your existing file content to your Amazon FSx file system, the data will be continuously getting deduplicated, and your overall data set can fit in the smaller file system.  
  
Thank you,
